Transsphenoidal surgery is the main treatment of patients with adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas. Although biochemical remission occurs in most patients undergoing operations at specialized centers, the recurrence risk is significant. Visualization of microadenomas on preoperative imaging and confirmation of ACTH-positive adenomas have been associated with higher remission rates. Low cortisol levels in the first 2 weeks postoperatively have been associated with durable remission; however, recurrence cannot be excluded by any cortisol threshold...

Granular cell tumours (GCT) are rare, slow-growing, benign neoplasms that are usually located in the head and neck. They are more frequent in the female gender and typically have an asymptomatic clinical course, being diagnosed only at autopsy. Symptomatic GCT of the neurohypophysis are exceedingly rare, being less than 70 cases described so far. The authors report on a case of a 28-year-old male that presented to the Endocrinology clinic with clinical and biochemical evidence of hypogonadism. He also reported minor headaches without any major visual symptoms...

BACKGROUND: Thyroid nodules are a common clinical problem, and differentiated thyroid cancer is becoming increasingly prevalent. METHODS: Six scientific Italian societies entitled to cure thyroid cancer patients (the Italian Thyroid Association, the Medical Endocrinology Association, the Italian Society of Endocrinology, the Italian Association of Nuclear Medicine and Molecular Imaging, the Italian Society of Unified Endocrine Surgery and the Italian Society of Anatomic Pathology and Diagnostic Cytology) felt the need to develop a consensus report based on significant scientific advances occurred in the field...

The treatment objectives for a patient with Cushing's disease (CD) are remission of hypercortisolism, adequate management of co-morbidities, restoration of the hypothalamic-pituitary-adrenal axis, preservation of fertility and pituitary function, and improvement of visual defects in cases of macroadenomas with suprasellar extension. Transsphenoidal pituitary surgery is the main treatment option for the majority of cases, even in macroadenomas with low probability of remission. In cases of surgical failure, another subsequent pituitary surgery might be indicated in cases with persistent tumor imaging at post surgical magnetic resonance imaging (MRI) and/or pathology analysis of adrenocorticotropic hormone-positive (ACTH+) positive pituitary adenoma in the first procedure...

It is now well accepted that exposure to adverse environmental conditions in utero can predispose a fetus to disease later in life. Using an avian model to study the programming of disease has a unique advantage as it allows isolation of the direct effects of adverse conditions on fetal physiology, without any confounding effects via the mother or placenta. However, experiments in avian models are limited by the lack of well-established surgical protocols for the adult bird, which we have established in this study...

Many systemic diseases or conditions can affect the maxillofacial bones; however, they are often overlooked or incidentally found at routine brain or head and neck imaging performed for other reasons. Early identification of some conditions may significantly affect patient care and alter outcomes. Early recognition of nonneoplastic hematologic disorders, such as thalassemia and sickle cell disease, may help initiate earlier treatment and prevent serious complications. The management of neoplastic diseases such as lymphoma, leukemia, or Langerhans cell histiocytosis may be different if diagnosed early, and metastases to the maxillofacial bones may be the first manifestation of an otherwise occult neoplasm...

INTRODUCTION: The endoscopic endonasal approach has become the gold standard for the surgical treatment of pituitary adenomas. OBJECTIVES: The aim of this study is to present the results obtained in our hospital in purely endoscopic surgery of pituitary adenomas. METHODS: From February 2011 to August 2016, we conducted a prospective study on a series of 86 patients with pituitary adenoma, all of whom underwent surgery with a purely endoscopic endonasal approach...

Hypoparathyroidism is a rare disease characterized by low serum calcium levels and absent or deficient parathyroid hormone level. Regarding the epidemiology of chronic hypoparathyroidism, there are limited data in Italy and worldwide. Therefore, the purpose of this study was to build a unique database of patients with chronic hypoparathyroidism, derived from the databases of 16 referral centers for endocrinological diseases, affiliated with the Italian Society of Endocrinology, and four centers for endocrine surgery with expertise in hypoparathyroidism, to conduct an epidemiological analysis of chronic hypoparathyroidism in Italy...

OBJECTIVE: To review tracheal paragangliomas and describe the clinical presentation, radiologic findings, operative management, and histologic findings of a pediatric patient who presented with stridor refractory to traditional asthma therapy. METHODS: Chart review of an 8-year-old male who presented to a tertiary care pediatric hospital and literature review of tracheal paragangliomas. RESULTS: We present the case of an 8-year-old male who presented with new-onset of wheezing and dyspnea on exertion...

OBJECTIVES: It is well-known that Rathke's cleft cysts (RCCs) infrequently cause headache, endocrinological dysfunction, and visual disturbance, and in rare cases, cause diabetes insipidus (DI). Although surgical evacuation of the cyst content can result in high rates of symptomatic improvement, not only the treatment efficacy but also the pathophysiology of DI with RCC are undetermined. The aim of this study is to elucidate the underlying mechanisms and outcomes of DI associated with RCCs...

Adrenocortical carcinoma is a very rare and aggressive endocrinological malignancy arising from the adrenal cortex. The estimated incidence is 1 per million people, with an estimated 5-year survival rate of 16-47%. It can be bilateral in roughly 2-10% of cases, but the data is scarce and there is no conclusive evidence whether the contralateral mass is an independent tumor or a metastasis from the other adrenal gland cancer. Radical surgical excision is the only curative treatment. Therefore, careful pre- and intraoperative surgical planning is critically important...

OBJECTIVE: To describe the level of interest in the fellowship in minimally invasive gynecologic surgery (FMIGS) using data from National Residency Match Program (NRMP) over the past 4 years. DESIGN: Retrospective report (Canadian Task Force Classification II-2) SETTING: Publically reported data from the NRMP PARTICIPANTS: Applicants using the NRMP to match into fellowship training. INTERVENTIONS: Reporting matching trends for the gynecologic surgical subspecialty programs starting in 2014, when the FMIGS programs started participating in the NRMP...

BACKGROUND: Adrenal masses are a known extraintestinal manifestation of familial adenomatous polyposis. However, the literature on this association is largely confined to case reports. OBJECTIVE: This study aimed to determine the characteristics of adrenal masses in familial adenomatous polyposis and their clinical significance, as well as to estimate their prevalence. Mutational analysis was conducted to determine if any potential genotype-phenotype correlations exist...

Transient intussusception without any underlying lead is a rare clinical entity which can cause abdominal pain in adults. It has been associated with inflammatory bowel disease, cystic fibrosis, and endocrinological disorders. We present a case of transient jejunojejunal intussusception in a 42-year-old Hispanic male patient without any underlying pathological lead point. Surgical intervention yielded a negative laparotomy and resection was not undertaken. We discuss the clinical presentation, surgical procedure, risk factors leading to episodes of transient intussusception, and the use of surgery versus conservative management in such cases...

BACKGROUND: Pituitary apoplexy is an uncommon, potentially fatal condition due to spontaneous ischemia or hemorrhage in a pituitary adenoma. The treatment of this disorder has long been a matter of debate. METHODS: Retrospective cohort study including all patients admitted with pituitary apoplexy in our department between 2005 and 2015 was undertaken. Clinical symptoms and signs on admission, treatment (conservative vs. surgical), neurologic deficit on discharge and at 6 months' follow-up, and endocrinologic evaluation at 6 months' follow-up were analyzed...

BACKGROUND: IgG4-related hypophysitis is a rare clinical entity that forms part of an emerging group of multi-organ IgG4-related fibrosclerotic systemic diseases. The rare prevalence of the disease, presenting features that overlap with other sellar pathologies, and variable imaging features can make preoperative identification challenging. PURPOSE AND METHODS: We report three cases of isolated IgG4-related hypophysitis with atypical clinical and imaging features that mimicked those of pituitary apoplexy and other sellar lesions...

The study aimed to retrospectively analyze the clinical characteristics of patients with pituitary adenomas complicated by acromegalic cardiomyopathy and to evaluate the effect of endoscopic surgery. Eighty-six pituitary adenoma patients complicated by acromegalic cardiomyopathy who were treated with endoscopic surgery in the First Affiliated Hospital of Soochow University from January 2010 to December 2016 were enrolled. We noted patient clinical characteristics and explored the relationships with surgical treatment...
